Where do you find to be the cheapest / least expensive place to buy pool chemicals? I suppose I'll always have to go to the local store for jugs of chlorine or acid but what about all the other stuff like calcium, alkalinity, stabilizer, algecide, etc.? Can these things be purchased online and if so, are there any reputable online dealers where the savings are significant? What about places like Walmart or Home Depot? Just curious where people go to save money on chemicals.
Thanks in advance!
